Subject: [PATCH] Dump the data only in DEBUG builds
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit

Also use -Werror only in DEBUG builds, otherwise normal builds fail with:

src/am7xxx.c:42:13: error: ‘dump_header’ defined but not used [-Werror=unused-function]
src/am7xxx.c:73:13: error: ‘dump_buffer’ defined but not used [-Werror=unused-function]
